I would love to see the bunker in Russia all those spam cans came from. I bet those things were stacked 100 feet high.
they're only stacked about 80 ft high these days.
seriously, I do wonder how much of the "supply" we've actually imported into the country. My guess is that there is much, much more still sitting in bunkers still. We may have only seen the tip of the iceberg.
We can hope.
That's what I do too, even though I have the proper "can opener". If you grind the lip off nice and smooth, you can even re-use and re-seal the can.Or an angle grinder used along the top edge may work. Just grind through the sealed edge. And though it shouldn't affect anything, I'd try to keep heat to a minimum.
